Named the Wraith, the car is essentially a coupe version of the four-door Ghost. Rolls-Royce, a subsidiary of BMW, hasn't released details on the car's power. But in a statement announcing the Wraith, Rolls-Royce promised the car "will be the most dynamic, powerful and beautiful Rolls-Royce in the company's history."

That means it will need to squeeze more than the 563 horsepower and 575 pound-feet of torque the Ghost is currently pulling out of a 6.6-liter, direct injected V-12 motor. That's enough power to move the 5,200-pound sedan from zero-60 mph in 4.7 seconds. Expect the Wraith's time to be less.

The car will premiere at the Geneva Motor Show in March and will likely go on sale at the end of the year. When it does, it will join the Ghost and the larger (but less powerful) Phantom, Phantom Coupe, and Phantom Drophead Coupe -- Rolls-Royce speak for convertible -- in its lineup.
